FASTENER.

Specicaton of Letters Patent.

Patented sept. 1o, 191.2..

Application filed April 8, 1912. Serial No. 689,367.

ation, and neatness `of appearance.

@To the above ends my invention consists insuch parts and combinations of parts as fall within the scope of the appended claim. Inl the accompanying drawings -which form a part of this specification,- wherein like characters of reference indicate like parts throughout the views, Figure l is a side elevation -of my. fastener in engaged position and attached to a chain, Figs', 2 and 3, a bottom plan view and a side elevation respectively of myl fastener in engagement, Fig. 4 a side elevation of the fastener parts detached, and Fig. 5, a perspective vie'w of the fastener parts in partially engaged position,

In'the accompanying drawings, Al indicates a receiving member and B an engaging member of my complete fastener. The receiving or engaged member A is constructed preferably of wire and comprises an oblong body consisting of an intermediate reduced portiona formed by two parallel wire legs forming a resultant slot or passage b. Con- 'tinuous with one end of the intermediate or body portion a is a small loop C forming an opening o continuous with the passage b but of greaterdimensions. Continuous with the opposite end of the portion is a loop D forming an openin d of greater diameter than the opening o. ntegral with or iiXed to the loop D is al ring or eye E adapted to receive the end link f of a chain or flexible member F with which the fastener is intendedto be used.

The member B comprises a rodlgv provided upon its outer end with an integral loop H adapted to receive the opposite end link i of the flexible member F. Thev opposite end of the rod g is bent, as at y', to form a finger J disposed at substantially right angles to the rod g. The finger ,J terminates in a spherical member or ball K. At a point intermediate its length the rod has its opposite sides .compressed to create opposite cavities L forming a reduced portion n.

My fastener is operated as follows: The members A and B are positioned relatively to eachother as indicated in Fig. 4 with the ball K immediately over the larger opening d in the member B, which opening is of sufficient dimensions to readily permit the passage of the ball K therethrough. The ball is then downwardly passed throiigh the opening d until the reduced portion n of the rod g comes into thehorizontal planeof the body a, whereupon the portion n is slid through the passage b, the rod g being for this purpose held at substantially right angles to the member B. Vhen the rod g-has reached the opening o, therod is brought into a horizontal position with the finger J engaging the end of the loop C while the parts *areI held lin engagement, since the opening c is of less dimensions than the openi'ig d and of less dimension than the ball K, so that lthe ball cannot esca e upwardly through the opening c. The iameter of therod g being in excess of the width of the slot or passage b, the member B cam not under normal yconditions escape by any horizontal movement from the member A. The disengagement can obviously only take place by tilting the member B inwardly at .substantially right angles to the member A and reversing the described operations.

What I claim is,

In afastener, the combination of.a re-A and its bent portionbeing of greater diame- ,opening of the receiving member and of too great dimensions to pass through the smaller l opening thereof.

n testimony whereof haya aixed my signature in presence of two Witl'u'ssses.
